I'm looking for plans,kits,completre conversions of Bud Rinker's gear drive conversion for Corvair engines. I'm interested in purchasing any plans,kits or ,conversions available. Also would like to know if anyone is flying a Rinker Redrive today. This seems like the correct  conversion for Corvairs; no crank breakage, and the reduction ratio puts the Corvair in the proper torque curve unlike the direct drive Corvairs.   Any response would be appreciated.

happy

HI

WHAT I KNOW ABOUT THE RINKER IS    IT WAS  VW VAN REDUCTION(GEAR BOXES) MOUNTED ON THE REAR AXEL SUPPORT CLOSE TO THE WHEELS,\. THESE WERE HEAVY UNITS BUT THEY WORKED AND ARE STILL AVAILABLE FROM JUNK YARDS. THEY WERE OF MARGINAL STRENGTH.

A BETTER UNIT IS A (VALLEY ENGINERING)  REDRIVE  AS IT IS MUCH LIGHTER WITH DIFFERENT RATIOS.

THANKS GUY KELLY

BUS BOYS sells used parts for the VW box,they were available in 1:39,1:69,and1:89 ratios.   SPORTS SPECIALTIES makes custom ratios for the VW box in up to 2:1 . What I'm really l;ooking for is a set of plans.     THANKS WILEY

Are you SURE you don't know where to find them?

William, I'm the owner of the CorvAIRCRAFT e-mail list where you posted this same question, then went about to answer it. It seems that you already know about the redrive and are attempting to draw attention to it and the current plans owner.

By the way, a cheaper, lighter insurance policy against crank failures on the Corvair is a fifth bearing. And it doesn't add another point of failure to the mix, that being the accessory end of the crank not to mention the PSRU itself. The only person that I know of who ever flew the Rinker (Bud Rinker and Richard Finch never succeed) had two failures of the harmonic balancer keyway as it was used to support the starter gear. Seems that gear lash was partly if not completely to blame.

As for "proper torque curve" that would be subjective. Higher RPM will just reduce TBO. There's no way around that. 

The Rinker is a heavy piece of cast iron with internals that were never designed to spin nearly as fast as they do on an airplane engine and were never designed for 100+ horsepower. It's the drive gear from a VW bus tansaxle that maybe saw 20 horsepower and rarely over 800 rpm. For the Rinker to actually be a useful PSRU, the engine would need to spin in excess of 4,000 rpm, five times what it was ever intended to deliver in the bus.

Plus, there is no provision for a thrust bearing. A VW bus never saw any continuous side loads that would compare to 100 hp worth of thrust for hours on end.

Patrick Panzera,the sometimes editor of CONTACT magazine. I find your statements to be funny ,erroneous,if not humorous. Why was I taken off the Corvaircraft LIST?    Mr. know-it-all,I would like to hear an answer!    Wiley

Hey PP,

Your a fine one to comment about someone else's attitude. You have a picture of yourself for your avatar, then highlight it with all those cute little badges from the clubs you joined in a cheesy attempt to make yourself look good. You've got a pampas a$$itude that's off the chart.  Then to compound your little man syndrome you have a reputation for spouting your mouth off. Here's a thought for you. Maybe you could apply to the EAA and become the forum police. Then they would give you another badge to put under that picture of yourself.
